A toy rocket engine is securely fastened to a large puck that can glide with negligible friction over a horizontal surface, taken as the xy plane. The 4.00-kg puck has a velocity of 3.00î m/s at one instant. Eight seconds later, its velocity is (8.00î + 10.00ĵ) m/s. Assuming the rocket engine exerts a constant horizontal force, find:
(a) the components of the force
(b) its magnitude.
